I Improvements in Fasteners, of which the following is a specification,reference being had to-the accompanying drawings.

This invention relates to certain improvements in fasteners and hasrelation more particularly to a device of this general characterespecially designed and adapted for use in connection with boxes or thelike for temporarily retaining a cover inapplied position; and it is anobject of the invention to provide a novel and improved device of thisgeneral character which may be applied with convenience and facility andwhich serves to effectively maintain a lid or cover in applied position.a

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved fastenerwhereby eertain important advantages are attained and-the device isrendered simpler, less expensive and otherwise more convenient andadvantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will hereinafter be definitelyclaimed.

In order that my invention may be the better understood, I will nowproceed to describe the same with reference to the accompanyingdrawings, wherein Figure 1 is a view in perspective illustrafing afastener constructed in accordance with an embodiment of my inventionand in applied position; Fig. 2'is a view in elevation of the fasteneras disclosed in Fig. 1; Fig. 3 is a vertical sectional view takenthrough the fastener as disclosed in the preceding figures; and Fig. 4is a View in perspective illustrating a fastener constructed inaccordance with a further embodiment of my invention and in appliedposition.

In practice it is desired to employ at least two of my improvedfastenersin connection with a single lid or cover but as theconstruction of all of the fasteners is intended to be substantially thesame, it is thought that a description of a single fastening dc vice issufficient for the ,purposes of disclosure.

As disclosed in Figs. 1 to 3, 1 denotes an elongated plate provided atone end with the returned portion 2 whereby the same may straddle theupper edge of a box or thelike, and thereturned portion 2 isprovidedwith the inwardly directed penetrating points,

while'cthe'portion of the plate .opposed'to the returned portion 2 hasstruck therefrom the downwardly directed tongue 3 which is adapted to beforced inwardly in a manner which will hereinafter be more particularlyset forth. The tongue 3 is also provided with an inwardly directed prong4 for a purpose which is also believed to be selfevident.

The vertical marginal portions of the 5 the tongue 3 and which serve assupports for the cross pin or pintle 6 with which is operatively engageda member M for forcing the tongue 3 inwardly in order to as sure aneffective engagement of the device in itsentirety to a wall of a box orthe like.

As herein embodied,the member Mcomprises an elongated plate of materialhaving its longitudinal margins at one end portion thereof returnedtransversely, as indicated at 7 to afford an effective means whereby therequisite rocking movement may be imparted to the member, while theopposite longitudinal marginal portions of thcmemher are returnedlongitudinally, as at S, to afford knuckles through which the pin orpintlefi is directed, and whereby the member M is capable of rockingmovement.

The portion of the member M between the eyes 8 and in advance thereof isinwardly directed to afford a cam 9 which, upon downward rockingmovement being imparted to the outer end of the member M, serves toforce the tongue 3 inwardly toward the side of the box or the like withwhich the device is engaged.

The upper portion of the plate 1 is provided at opposite sides of thereturned portion 2 with the longitudinal marginal extensions 10 ofpredetermined length and which are bent upon the box B, while thevertical portions or feet 11 of said extensions 10 are adapted to bridgethe adjacent edge of the lid or cover as is thought to be clearly shownin the accompanying drawings.

The form of invention illustrated in Fig. l is substantially the same ashas hereinbefore been set forth except that each of the extensions 10 issubstantially U-shaped in form with the upper stem thereof of a greaterlength than the lower stem and with the intermediate or base portionthereof positioned a predetermined distance in advance of the plate lWith this form of my invention it will be perceived that a lid or coverL need not be of an area substantially equal to the area of the box B,but can be of a greater size.

It will be understood that my improved fasteners are adapted to beemployed in connection with boxes containing merchandise which issusceptible to injury when the top or lid is removed and affords aneffective medium whereby the lid or cover may be temporarily maintainedin applied position upon the container.

From the foregoing description, it is thought to be obvious that afastener constructed in accordance with my invention is of an extremelysimple and comparatively inexpensive nature and is particularly welladapted for use by reason of the convenience and facility with which itmay be assembled, and it will also be obvious that my invention issusceptible of some change and modification without material departurefrom the principles and spirit thereof and for this reason I do not wishto be understood as limiting myself to the precise arrangement andformation of the several parts herein shown in carrying out my invention in practice, except as hereinafter claimed.

I claim:

1. A fastener of the class described comprising a plate having an endportion returned, a tongue struck from the plate and opposed to thereturned portion thereof, angular extensions carried by the end of theplate at opposite sides of the returned portion thereof, and meanscarried by the plate for forcing the tongue inwardly toward the returnedportion thereof.

3. A fastener of the class described comprising a plate having an endportion returned, a tongue struck from the plate and opposed to thereturned portion thereof, angular extensions carried by the endof theplate at opposite sides of the returned portion thereof, said platebeing provided at opposite sides of the tongue with the returnedportions afiording knuckles, a pin mounted in said knuckles and disposedtransversely of the tongue, and a member pivotally engaged with said pinand coacting with the tongue for forcing the same inwardly.

4. A fastener of the class described comprising a plate having an endportion returned, a tongue struck from the plate and opposed to thereturned portion thereof, angular extensions carried by the end of theplate at opposite sides of the returned portion thereof, a pin disposedtransversely of the plate at a point substantially midway the length ofthe tongue, and an elongated member provided adjacent one end withreturned portions affording knuckles through which the pin is directedand whereby said member is capable of rocking movement, the portion ofthe member inwardly of the knuckles being angularly disposed in adirection toward the tongue and adapted to contact with the tongue uponrocking movement of the member in one direction for forcing the tongueinwardly.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.
